Test Results

The TPS6290xEVM-069 was used to take all the data in the TPS62903, 3-V to 17-V, Low IQ Buck Converter in 1.5 mm × 2 mm QFN Package data sheet. See the device data sheet for the performance of this EVM.

Figure 4-1 shows the thermal performance of the EVM. "Spot" shows the temperature of the PCB. Figure 4-2 shows the loop response measurement.
